Yes, you read that right. The Ferrari
500 TRC (Testa Rossa Type-C) Spider was one of the last Ferraris built with an inline-four. It's engine was designed by Aurelio Lampredi for Formula Two, but Ferrari dropped the engine altogether when the engineer left the company. This was also the first Ferrari to have the Testa Rossa name. In fact, it's even more rare than the more powerful V12-powered 250 TR and 250 GTO.
